Treatment of Hypothalamic Obesity With GLP-1 Analogs.

Introduction: Congenital and acquired damage to hypothalamic nuclei or neuronal circuits controlling satiety and energy expenditure results in hypothalamic obesity (HO). To date, successful weight loss and satiety has only been achieved in a limited number of affected patients across multiple drug trials. Glucagon-like peptide-1 (GLP-1) acts via central pathways that are independent from the hypothalamus to induce satiety.

Long-term outcome of childhood and adolescent patients with craniopharyngiomas: a single center retrospective experience.

Background: The treatment of craniopharyngiomas (CPs) poses challenges due to their proximity to critical neural structures, the risk of serious complications, and the impairment of quality of life after treatment. However, long-term prognostic data are still scarce. Therefore, the purpose of this retrospective study is to evaluate the long-term outcomes of patients with CPs after treatment.

Predictors of mortality at 3 months in patients with skull base tumor resections in a low-income setting.

Objective: Globally, skull base tumors are among the most challenging tumors to treat and are known for their significant morbidity and mortality. Hence, this study aimed to identify robust associated factors that contribute to mortality of patients following surgical resection for a variety of skull base tumors at the 3-month follow-up period. This in turn helps devise an evidence-based meticulous treatment strategy and baseline input for quality improvement work.

Modeling craniopharyngioma for drug screening reveals a neuronal mechanism for tumor growth.

Tumors occurring along the hypothalamus-pituitary axis receive axonal projection from neuroendocrine neurons, but it remains unclear whether neuroendocrine neuronal activity drives tumor expansion. Craniopharyngioma is a common suprasellar tumor with a propensity for invading the hypothalamus, leading to devastating endocrine and metabolic disorders. Here, we developed two autochthonous animal models that faithfully recapitulate the molecular pathology, clinical manifestations, and transcriptomic profiles of papillary craniopharyngioma.

A Fusion Model of MRI Deep Transfer Learning and Radiomics for Discriminating between Pilocytic Astrocytoma and Adamantinomatous Craniopharyngioma.

Rationale And Objectives: This study aimed to develop and validate a fusion model combining MRI deep transfer learning (DTL) and radiomics for discriminating between pilocytic astrocytoma (PA) and adamantinomatous craniopharyngioma (ACP) in the sellar region.

Methods: This study included 348 patients with histologically confirmed PA (n = 139) and ACP (n = 209). Data were randomly divided into training and testing cohorts in a 7:3 ratio.

Advancements in Molecular Diagnosis and Pharmacotherapeutic Strategies for Invasive Pituitary Adenomas.

Background: The overwhelming majority of pituitary tumors consist of pituitary adenomas (PAs), which have recently also been termed pituitary neuroendocrine tumors (PitNETs). Clinically significant PAs occur in approximately one in every 1000 individuals, while other types of pituitary tumors, such as craniopharyngiomas and pituicytomas, are significantly less common. Although PAs are generally benign, a subset of them exhibits malignant-like biological traits.

A novel multilayered membrane repair technique for high-flow cerebrospinal fluid leaks during expanded endoscopic endonasal tumor resection.

Background: Postoperative cerebrospinal fluid (CSF) leak is a life-threatening complication following endoscopic skull base surgery. This study describes a multilayered membrane reconstruction strategy for treating high-flow intraoperative CSF leaks during expanded endoscopic endonasal tumor resection (EEA) and presents the associated outcomes, supplemented by surgical video documentation.

Methods: A retrospective review was performed on patients who underwent multilayered membrane reconstruction for high-flow CSF leaks during EEA.

Diagnostic considerations of tumors of the sellar region according to their geometry and vector growth.

Introduction: Sellar and parasellar tumors are frequent lesions in neurosurgical practice, highlighting pituitary adenomas, craniopharyngiomas, and sellar tubercle meningiomas. The clinical manifestations are similar, however; There are imaging aspects that differentiate them.

Objective: Show imaging aspects of tumors in the sellar and parasellar region that guide their histopathological diagnosis.

Perioperative Management of a Child With Pre-existing Diabetes Insipidus Undergoing Craniopharyngioma Excision: A Case Report.

Craniopharyngiomas are rare tumors arising in the suprasellar area of the brain and are more common in the pediatric age group. Due to the involvement of the hypothalamus, central diabetes insipidus (DI) is usually associated with such lesions. Patients with DI are at risk for significant electrolyte disturbances due to high urine output and the potential for sodium imbalance.

[Pituicitoma in a patient with neurofibromatosis type 1].

Pituicytoma is a rare low degree tumor that arises from pituicytes in the infundibulum and posterior pituitary gland. As they do not have characteristic radiological features, they can be misdiagnosed as pituitary adenoma, meningioma, or craniopharyngioma. Clinically, patients can present with hormonal disturbances, headaches and visual field defects.

Clinical response to dabrafenib plus trametinib in BRAF V600E mutated papillary craniopharyngiomas: a case report and literature review.

Papillary craniopharyngiomas are rare tumors prevalent to the precision oncology world due to their high rate of BRAF V600E mutations. Symptoms include vision loss, neuroendocrine dysfunction, and cognitive dysfunction. Treatment involves an interdisciplinary approach with surgery, radiation, and systemic treatment.

Practical application of precision oncology in adult onset craniopharyngiomas.

Introduction: Craniopharyngiomas (CPs) are benign and rare tumors found in adults. Their location close to vital neurovascular structures makes traditional treatment modalities (surgery and radiation) challenging and potentially fraught with morbidity. The 2021 WHO classification has divided what was previously considered two subtypes of craniopharyngioma into separate entities.

Endoscopic transsphenoidal surgery for infradiaphragmatic craniopharyngiomas and impact of diaphragm sellae competence on hypothalamic injury.

Investigate the impact of diaphragm sellae competence on surgical outcomes and risk factors for postoperative hypothalamic injury (HI) in patients undergoing endoscopic transsphenoidal surgery (ETS) for infradiaphragmatic craniopharyngiomas (ICs). A retrospective analysis of 54 consecutive patients (2016-2023) with ICs treated by ETS was conducted. All tumors originated from the sellar region inferior to the diaphragm sellae and were classified into two subtypes in terms of diaphragm sellae competence: IC with competent diaphragm sellae (IC-CDS) and IC with incompetent diaphragm sellae (IC-IDS).

The oxytocin system in patients with craniopharyngioma: A systematic review.

Craniopharyngioma is a benign tumour affecting the hypothalamic and pituitary regions, which are involved in the production and secretion of oxytocin. We conducted a systematic review to assess dysregulation of the oxytocin system in craniopharyngioma and associations with neurobehavioural, eating, and metabolic abnormalities. Eight studies (n = 72 patients) were included.

Length of stay following elective craniotomy for tumor resection in children and young adults: a retrospective case series.

Purpose: Length of stay (LOS) is a critical metric of healthcare delivery. Prolonged LOS is associated with a heightened risk of adverse complications. We aimed to provide a comprehensive evaluation of LOS, specifically identifying variables associated with extended LOS (eLOS), in children and young adults following elective craniotomy for tumor resection.

Impact of stereotactic radiotherapy for craniopharyngioma: a large, academic hospital cohort.

Purpose: Adjuvant radiotherapy has been a standard of care for craniopharyngioma. Nevertheless, it is a rare disease with multiple presentations, and results with conservative surgery followed by radiotherapy (RT) can vary. We compared treatment results for both adult and pediatric patients.

Ferroptosis-related biomarkers for adamantinomatous craniopharyngioma treatment: conclusions from machine learning techniques.

Introduction: Adamantinomatous craniopharyngioma (ACP) is difficult to cure completely and prone to recurrence after surgery. Ferroptosis as an iron-dependent programmed cell death, may be a critical process in ACP. The study aimed to screen diagnostic markers related to ferroptosis in ACP to improve diagnostic accuracy.
